turning up the fuel

[blasini]

Hello all,


well i turned the fuel up on my m109a2 on sunday. I went 8 flats on the fuel rod nut. wow what a difference. A lot less shifting now. Don't have to use low range either to start out. Cruises a lot easier too. Also would like to give an update on the air assist steering. Increditable to say the least. Its drives like a normal truck. It steers much better and the road feel is excellent.



I ordered a pyrometer and boost gauge from napa. I think i should put one on to be safe. I think 8 flats on the rod has to be around 50hp. Black smoke comes out when goosing engine but burns clean at cruising spped. No more downshifting to 4th now on small hills.

That's about right. If your smokin while crusing then it's too rich. Once you get the pyro you can fine tune it where it will make the most power with out getting the egt's too high.

Define too high? my gauge reads in degrees C. I have felt that I should tweak my fuel setting a little as well. Looking for tips from people who have done it.

Well, 1,200 F is 648 deg C and that is generally considered the max safe EGT.

CAn you post the part numbers of the gauges from Napa? My sister in-law works there and I get parts at cost +10%! I love my brudda!

Don't forget smoke is progress!!

Can the fuel be turned up on the NON turbo engines as well?

 

[bomar76]

Sure.
Just remember more fuel= more heat as in higher Exhaust Gas Temps
Aluminum (your pistons) melt at 1300º F

Blasini,
$180 for a pyrometer is a bit rich for me................

Paid $20 for my pyro gauge at a truck salvage yard. It is pretty old, made by Hewitt and has served me well for a couple of years now.
The thermocouple was bought new, also by Hewitt for about $40.
The boost gauge is an industrial pressure gauge, cost me about $10 new, It doesn't have night time illumination, but that's not a biggie, I keep a flashlight handy.
